Normally BMW only gets a chance to gouge you at the point of purchase. But new performance parts being released by its M Sport division mean Bimmer gets another shot at your wallet.

The line of parts is focused at the M5 and M6, which makes sense as the two are virtually mechanically identical.

Still, though, if you own an M5 Sedan, M6 Coupe, M6 Convertible, or M6 Gran Coupe, you might just be interested.

BMWs are always fabulous to drive, but sometimes they can be a bit…boring. One way to address this is with the aftermarket M exhaust now being offered. The Performance Exhaust System is was developed BMW M GmbH in partnership with exhaust specialists Akrapovic.

This special Performance Exhaust System will bring the noise.

Made of titanium, it is 22 pounds lighter than the standard exhaust, but the real point of this add-on is the noise. BMW says it “further enhances the characteristic sound” of the twin-turbo V8. Translating that statement from boring engineer speak to BMW customer language: “people will now look at your shouty $100,000.00 M car when you drive by.” I think it’s going to be great.

The other big additions to the lineup are BMW M Sport’s massive carbon-ceramic brakes. These are a $9,700 option at the dealership, so I shudder to think what they are going to cost in the aftermarket. Regardless of cost, they are going to be very, very good. The brakes are 16.1 inches in the front and 15.6 in the rear, yet weigh just 42.8 lbs.

No word on how much this carbon fiber trim will cost, but given that it comes from BMW, it won’t be cheap,

BMW has also provided some aesthetic upgrades, including an Alcantara leather steering wheel with an F1-style racing display. If that’s not your speed, you can trim everything from the shift lever to the mirror caps in carbon fiber.

All this carbon fiber won’t come cheap. But as I am sure BMW would tell you it’s a small price to pay for perfection.
